260 Protestant REPORTS of abuse vs 13,000 CREDIBLE Catholic reports of abuse.

That's 260 protestant reports PER YEAR vs 13,000 Catholic reports since 1950. I believe that works out to 228 per year for Catholics, 260 per year for Protestants. Or, since 1950, 13,000 for Catholics and 14,820 for Protestants.
It's worth pointing out that the 13,000 credible reports for Catholics cover everything but the reports for Protestants are for only the three insurance companies in the article. Apparently there are 224,000 Protestant churches in the US and the 260/annual number only covers 165,495 leaving 58,505 unaccounted for.
Furthermore even though 3 insurance companies were discussed only the report numbers for two of them were added into the total because one of the companies didn't have a breakdown based on the age of the alleged victims.
NOBODY should think this shows a bigger problem for Protestants though, Protestant congregations outnumber Catholic parishes by about 10/1.
For me it's immaterial what the Protestants get up to, we have our own problem.
